Same thing here. You have won airmiles" BS. 6:43pm. You call back and it is a number that has not been assigned. Why can't the phone companies fix this crap?
Just missed a call from this number. Since it was a BC area code I thought it might have been from my daughter who is travelling in BC today. When I called back I get a "number not is service message". Appears to be another telemarketer who does not want to be identified.
I've had several calls to my cell phone in the last couple of weeks with the same recorded message as ANON. I would think this was more of the same.
